broad pale vitta over the front portion. The 
dark colors on the thorax vary from pale 
brown to blackish brown but are not jet black 
as in dorsalis. Legs: The coxae and trochanters 
are yellowish tinged with brown. The front 
and hind tibiae are brown to black. The mid- 
dle pair are yellow on their apical halves. The 
femora are yellow except for a large brown 
spot on the outside dorsal surface of the apical 
third of each front femur. Wings: As in dorsalis 
except for the shorter third costal section 
(stigma) (Eig. 5^). The costal cells are hya- 
line, and the costal band is not attenuated at 
apex (refer to discussion under D. froggatti 
(Bezzi)). Abdomen: As in dorsalis, but the 
markings are more brown in color. 
Length: Body, 6. 0-6. 4 mm.; wings, 5.1 mm. 
FEMALE. As in the male except for genital 
characters. Ovipositor: The exposed portion of 
the ovipositor is slightly shorter than the fifth 
abdominal segment. The extended ovipositor 
(Fig. 5c) measures 3.5 mm. in length. The 
basal segment is approximately 1.3 mm. long 
by 1.0 mm. wide at its broadest point. The 
spiracles are situated about 0.31 mm. from 
the base of the segment, measured on the 
lateral margins. The inversion membrane is 
about 1.2 mm. long by 0.3 mm. wide at its 
widest point. The rasper extends to within 
0.26 mm. of the base of the segment. The 
piercer is about 1.0 mm. in length by 0.21 
mm. wide at its widest point. The apex of the 
oviduct is about 0.23 mm. from the tip of the 
piercer. The preapical setae are small and in- 
conspicuous, the four pairs are equal in size 
(Fig. ^d), and the distal setae are approxi- 
mately 0.07 mm. from the tip of the piercer. 
In dorsalis the distal two pairs of setae are 
much more strongly developed than are the 
proximal pairs. 
Holotype male, allotype female, and 29 
paratypes, 19 males and 10 females: Singa- 
pore, Malaya, May, 1949, ex fruit of Areca 
catechu. Also, four paratypes, two males and 
two females, Beranang, Selangor, Malaya, 
June, 1948, ex Areca catechu. One male spec- 
imen is also on hand from Singapore, May, 
1949 , ex Canangium odoratum; it is not being 
designated as a paratype. 
The type, allotype, and a series of paratypes 
are in the U. S. National Museum. The re- 
mainder of the paratypes are in the following 
collections: Bernice P. Bishop Museum, Ha- 
waiian Sugar Planters’ Association, Territorial 
Board of Agriculture and Forestry, and the 
University of Hawaii. 
Dacus (Strumeta) cilifer Hendel 
Dacus cilifer Hendel, 1912, Suppl. Ent. 1: 15, 
pi. 1 , fig. 1 . 
This species is distinguished by the black 
transverse band across the face, the all-black 
abdomen, and by the elongate ovipositor, the 
basal segment of which is equal in length to 
abdominal segments three to five. It has been 
adequately described by Hendel and by Shi- 
raki (1933: 71-73). 
Length: Body, 4.0-6. 5 mm.; wings, 3.5- 
6.0 mm. 
TYPE LOCALITY: Formosa. Host, Momordica 
cochinchinensis Sprengel. 
Type in the Deutsches Entomologisches 
Institut. 
We have not seen this species. Perkins 
(1938: 127) recorded it from North Borneo 
and Malaya. 
Dacus {Strumeta) cognatus n. sp. 
Fig. 6 
This species is very close to D. dorsalis 
Hendel and can be separated satisfactorily 
only by the ovipositors. If the specimens are 
fully hardened, the markings of the mesono- 
tum and abdomen appear to be distinctive. 
The postsutural yellow vittae on the m^eso- 
notum are wedge-shaped and end slightly be- 
fore the inner supraalar bristles. The area 
around the inner supraalar is yellow brown 
and contrasts with the bright-yellow coloring 
of the vittae. In dorsalis the vittae are broad, 
parallel sided, and the inner supraalars are 
included within their boundaries. The sides
